Tool/Z 'ti/*tem it may concer/li y .Be 1t known that we.r Ennns'r G. FISCHER,

a citizen ci' the United States. yand HEIN? arci-I CONRAD llenarniviv, a subject oi' the Emperor of Germany, and residents ot'New l a specification.

This invention relates to improvements in hinged covers and methods of securing the same to receptacles and particularly to those tor household purposes as containers oi foods and beverages.

`@ne oi the principal objects is to provide a cover which may be applied to any ordinary vessel, such as a bowl, soup-tureen, stein, etc., the attachment being readily made without difficulty or delay. Y

A second object is to provide such covers, the greater portion of which is transparent, rather than opaque, ot such nature as to be free from danger of catching fire ilE used in cooking operations, which may be transferred from one vessel to another, and which may be washed or otherwise cleansed with entire facility.

A third obi ect is to provide a holder adapted to be resiliently secured upon vessels of the character described, and to which are attachable covers of varying size and shape, suited to vessels having different sized openings.

These and other objects, such as being capable oit' antiseptic treatmentand having a wide range of utility, are attained by the novel construction of parts hereinafter described, it being understood that minor modifications may be made without departing from the scope of the claims hereto appended.

Referring to the drawing: Figure 1 is a general perspective view or a bowl, showing the application of the invention. Fig. 2 is an enlarged fragmentary 'f section ot' the same, taken substantially on line 2.-2 ot Fig. 1. Fig. 3 is ay further enlarged fragmental view taken on lines 3--3 of Fig. 1. Fig. (l. is a partial elevational, partial sectional view of the holder showny ,in detail. Fig. 5 is a partial front view of the same. Fig. 6 is a perspective view looking from the interior of the cover holders, rshowing the hinged joints connecting the several parts;

Fig. 7 is a partial plan view of the hinge and cover plate securing means.

ln the several views, the numeral l0 des-V ignates the vessel upon -which the cover is applied, the Vsame showing a relatively deep, concave structure in the form or" a common bowl. The holding element is comprised ci' two thin plates and 16, respectively applied vertically to the interior and exterior wall of the vessel, the plates being curved lengthwise to suit, and connected rigidly together on their tops, which pass over the edge of the vessel. Formed with these platos sub* stantially in register with the outer edge or' the vessel, are hinges 17, one member of which is secured to a normally horizontal disposed leali' or plate 1S, having' near itsends'hook shaped lugs or'catches 22, each being open outwardly in opposite directions. also at-V tached by the hinges 17 is a second leatQ having openings 2S through which the catches extend when the leaves are closed together forming clamping elements Vbetween which' is removably secured a rim 35, acting as a. trame for the transparent cover plate 36, held rigidly between the leaves 18 and 27 when the bar 25 is swung upon the center pivot Q6, so as to engage with the hooks 22, as they extend through openings 29 in the trame and 28 in the leaf, locking the cover and its support rigidly together, the arrangement ot' cover supports and hinged elements being best shown in Fig. 6.

A transparent cover of non-inammable nature is preferred as by it cooking operations can be perceived and it adds materially to the advantage of the cover to be able to see through it; it will loe understood that the cover frame is made of non-corrodible material and suited to make intimate contact with the rim of the vessel; a stop 20, formed with the vertical support plates limits the raising of the lid or cover to a position substantially vertical with the vess sel. This construction permits an 'interchange of cover plates otvarying shapes and sizes to suit the vessels they are applied to, the holders being uniformly .the same throughout.

In order to maintain the holder securely upon the vessel, a hook 38 is engaged with the holder, its lower portion 39 being rigidly attached to a covered slideway 40 containing a coiled spring 41 exerting its force to draw the slide 42 upwardly, whereby the l part 42, having an upturned end 43, is caused to tightly engage with the beading usually formed at the bottom of a vessel. Thus provisions are made whereby the holder may be securely and easily attached to the vessel or removedv therefrom by merely detaching the hook element.

Having thus described our invention, what we claim as new and desire to secure by Letters Patent, is

l. In a device of the class described, the combination with a support detachably 'engaging the wall or' a vessel, of a pair of spaced leaves hinged independently to said support, means for clamping 'said leaves together, a transparent cover removably engaged with said leaves, and a stop formed with said support limiting the swinging movement of said leaves.

2. In a device of the class described, the combination with a support engaging the wall of a vessel, of a pair of leaves each individually hinged to said support, a transparent cover engageable between said leaves and means for detachably clamping said cover to said leaves.

3. In a device of the class described, a transparent cover plate, a containing frame circumjacent thereto,v said frame having a pair of perforations parallel with and equally spaced relative to a radial line, a support engaging the wall of the vessel, clamp leaves hingedly engaged with said support, said leaves being receptive of said frame, hooks formed with the lower of said leaves, the other leaf being perforated, and a clamp bar pivoted on the upper leaf, said bar being engageable with said hooks thereby clamping the cover plate rigidly.

Signed at New York, in the county of NewV York, and State of New York, this el-th day of December, A. D. 1915.
